Why is the UK shunning 3DS/WiiU harder than elsewhere? (Virtually absent from top 40)

[episteme]

The software charts are dominated by Western games.

Wii U only has ZombiU, LEGO City Undercover and some Western multiplats that are also on X360/PS3 or even X1/PS4.
3DS is dominated by Japanese games. It only has LEGO games, almost unplayable crap ports and shovelware from Western publishers.
